Testing DC Voltage with the PQR1010
The PQR1010 has one channels for analyzing DC Voltage.
This channel has a maximum input of +/-50V for testing low
voltage supplies.
Data from the DC input connector starts being collected as
soon as power is applied to the AC power connector located on the
back of the unit. Data will continue to be gathered until the unit is
powered down.
The PQR1010 samples the voltage on the DC input
continuously, and stores the average reading once each minute (or at
other selected intervals). There is enough data storage capacity in
the unit to collect these readings on this channel for 11 days.
The PQR1010 will continuously test the DC input for Sags,
Surges, Power Failures, Dropouts, Impulses, and High Frequency
Noise. Any power quality problems that exceed the preset
thresholds will be recorded in battery backed RAM, with the time
and date stamp of the event. There is enough data storage capacity
in the unit to collect up to 1500 of these readings.
